I think with the color you have picked for the body, the contrast will look really good. I'm not a painter, I have painted a lot years ago, but I was never a painter, if you know what I mean. But just a suggestion, when I start a new project I have my bodies chemically striped then they use a primer powder coating that is painter friendly. I know that doesn't apply to you but then I have them make up a half dozen spray cans with this stuff in it. It really works good. I wouldn't want to spray can a whole frame but for the smaller stuff it is easier than mixing everything up then cleaning everything up. I think I read in one of your post that you have a friend at a powder coater. If you think it is worth while maybe he could do the same for you.
